FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The specific function of this gene has not yet been determined; however, the protein it encodes is known to be a major constituent of the ARP2/3 complex. This complex is located at the cell surface and is essential to cell shape and motility through lamellipodial actin assembly and protrusion. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Mar 2013]
PHENOTYPE: Mice homozygous for a null allele die prior to E4.5 and exhibit abnormal embryogenesis. [provided by MGI curators]
